VEHICLErWHEEL.

T0 all'wkom it may concern:

Beitknown that I, GUSTAV SOHADEE, 'a citizen of the United States, residing in the borough of Manhattan, city, county, and

State of New York, have invented an Improvement in Vehicle-Wheels, of which the following is a specification.

This invention relates to a vehiclewheel and more-particularly to that form of ve- 'hicle wheel shown'and described inLetters Patent No. 1,215,924'granted to George S. Gallagher and myself on February 13, 1917,

which type of vehicle wheelis'especially adapted for use in motor trucks although it is understood'may be used for pleasure ve- Y hicles and other purposes.

In the form of the invention shown and described in the Letters Patent aforesaid,

- the mechanical features bywhich'the resiliency in the Wheel is effected comprise a series of pins adjustably secured in the felly and inner rim and extending between the inner rim and into a recess .provided therefor a flanged portion of the outer rim together with a spring surrounding each'of these rims and extending between the shoulder on the same andgthe face ofthe flanges on the outer rim. The strains ineluding the side thrust in the use of this form of wheel are likely in time to cause the parts to wear to such an extent as to -.materially impair their functions and consequently decrease the efliciency of the wheel, and the object of the present inven- -tion is to overcome this difliculty. The

wheel constructed in accordancewith my present invention, like the one shown and .described in the LettersPatent aforesaid, includes a hub, a felly, spokes connectingthe .hub and-felly, inner and outer rim members with pneumatic or other yielding tubes bemtween .the same, but-instead of employing the pins and springs to-which reference has j 1 hereinbefore been made I now prefer to employ series ofbrackets and pins connected .tothe-rface ofrthe felly, together with a .pluralityof-volute springs, one end of each 'ofwhich is connected to a pin fixed inthe corresponding bracket while the opposite end is suitabl secured in the outer rim of the wheel, these springs-being pla eq Specification of Letters Patent.

similar positions or, employed in sets of two placed'ln opposite positions as will be hereinafter more particularly described.

In the drawing Figure 1 is an elevation and partial cross cured at one end while at their opposite 1 ends these spokes are fixedin a felly 12.

Associated with the felly I employ an inner rim preferably comprising an inner rim member 13 and an inner rim member 1 1.

These inner rim members at one end are -'adapted to abut against the side portions of thefelly 12 and are provided with flanges 15 and 16 respectively adapted to engage a part of the face of the felly 12. In its opposite end the inner rim 13 is provided with a clamp 17 and similarly the inner rim 141 is provided with a clamp 18, these clamps being adapted to grip pneumatic tubes 19 and 20 respectively which are made part of the wheel, in a manner similar to that described in Letters'Patent aforesaid, it being understood that any suitable connections may be made between these pneumatic tubes for infiating'thesam'e and maintaining an equal pressure within them, The inner rim 'members may be secured to the Wheel in any suitable manner, for example, as shown 1 in the drawing,'by bolts 21.

Also associated with the felly and lying against the face thereof between the flanges i 15 and 16 I employ a series of brackets '22.

Each" of these brackets 22 includes spaced flanges 23' "and 24 depending therefrom and made in any suitable configuration. tending between and suitably secured in the outer portions of the flanges of each bracket is a pin 25, and each bracket may be suitfelly by means of bolts 26 or otherwise.

:I a p y a mite-"r m 21' T is employed to receive and maintain in position the outer portion of the pneumatic tube 20, these tube rings being suitably formed for this purpose. Furthermore the outer edge of each of these tube rings is preferably rou ded, roll d, orturnecl over, as indicated at 34t and extends appreciably beyond the side of the Corresponding pneumatic tube in order to protect the same as will be. readily understood. 7 Associated with each [of the brackets 22 1 employ a volute spring35, This spring is preferably made of flat metal, but asfivill be understood, in some instances may be .inade of round metal. When m'ade of'flat metal the widthof the'sa 'ne is approxiinately equal to the distance between the flanges 23 and 24L of the-brackets ,22 and when made of round metal the diameter thereof is such as to be approximately equal to the distance between these flanges. In either case one end of each spring is socurely fixed in the pin 25 secured in the flanges of the bracket with which the spring is associated, while the opposite end of'the spring is secured tothe. outer rim 27 by bolts 86 or otherwise. As indicated in Fig. 1 0 the dr i g I p e e o empl y the bracketS 22 and the springs associated therewith in pairs or sets of two, the convolutions of one spring being set in one directi n, While t e eonv ut ens of t e other spring are set in the opposite direction, the inner ends of the springs being connected to the pins associated with-their respective brackets while the outer ends of the springs are made so as to form a lap joint as indicated M37 in order hat same lts be employed to secure the outer ends of each p irefepringe gether a d t0 th o t im o he heel- However', e l str ed in VFig. 3,.the springs may be so connectedas t be ndependen ef a h other, and h springs so placed that the convolutions of th ame re e lin s m di e t on;
